+\subsection{False Positives}
+
+As can be deduced from table \ref{tab:infer}, Infer especially struggles at
+determining Vthe null safety of nested method calls or non-trivial data flow
+paths. This is sometimes caused by insufficient knowledge of the nullability
+contracts of the Java standard library (e.g. \textit{java.lang} package).
+
+In other cases, the flagged expression is guarded by an utility method throwing
+an exception if its value is indeed \texttt{null}. One of such guards is the
+\mintinline{java}{static Validate.notNull(Object, String, Object...)} method,
+which checks if its first argument is null and throws a
+\texttt{NullPointerException} if so.
+
+Additionally, Infer seems to struggle with boxed primitives and not
+understanding that their value is always non-null by construction. As an example
+I provide the warning reported in the file \textit{time/DurationUtils.java}:
+
+\begin{listing}[H]
+\begin{minted}[linenos,firstnumber=139]{java}
+public static int toMillisInt(final Duration duration) {
+    Objects.requireNonNull(duration, "duration");
+    // intValue() does not do a narrowing conversion here
+    return LONG_TO_INT_RANGE.fit(Long.valueOf(duration.toMillis())).intValue();
+}
+\end{minted}
+    \caption{Method \textit{toMillisInt(Duration)} of class
+    \textit{time.DurationUtils} in Apache Commons Lang 3.12.0.}
+\end{listing}
+
+Here Infer reports that the first argument of
+\mintinline{java}{LONG_TO_INT_RANGE.fit(Long)} may be null. However, the return
+value of \mintinline{java}{Long.valueOf(long)} is always non-null since the
+method simply boxes its \mintinline{java}{long} argument.
+
+Finally, some warnings are caused by Infer flagging the use of the \texttt{null}
+keyword as a method argument for methods that would accept a nullable argument
+in that position without causing null dereferences. This warning could point to 
+a potential ambiguity is selecting the right method to call at
+compile time given the argument types (i.e. static dispatching), as
+\texttt{null} is a valid expression of all object types. For example, in the
+given class:
+
+\begin{minted}{java}
+class C {
+  m(String s) {}
+  m(Object o) {}
+}
+\end{minted} 
+
+A call to \mintinline{java}{C.m(null)} would be ambiguous as \texttt{null} is
+both a \texttt{String} and an \texttt{Object}, thus a cast to either type woule
+be required to make the code compile. However, the warnings reported by Infer do
+not present such ambiguity as in those cases overloaded methods have different
+numbers of parameters. Additionally, even introducing explicit casts for all
+\texttt{null} arguments does not extinguish the warning. Therefore, I can not
+find a conclusive explaination on the nature of the false positive, however I
+can attest to these instances being indeed false positives by having manually
+verified that the methods in question indeed can accept a null value without
+causing null dereferences.
+
+\subsection{True Positives}
+
+In this section I now cover the warnings that are true positives and thus are
+causes for refactoring.
